"She had to meet Shia to see if they gelled," an on-set source told the magazine. "Having her in as little clothing as possible was just the icing on the cake. When she walked down a staircase in that outfit - wow.”

Last week, deadline.com confirmed that Jason Statham's girlfriend was Fox's successor in the third installment of Michael Bay's blockbuster.

Following the announcement, Victoria's Secret released a video montage congratulating Huntington-Whiteley on her first movie role.

The 23-year-old Brit became the "T3" front-runner - beating out Sarah Wright and SI cover girl Brooklyn Decker - after auditioning for Bay in early May.

The filmmaker only had a week left to decide who would take the place of Fox, who was reportedly fired because she lost too much weight.

"No matter what people spin or say, Megan Fox was fired," the source told Hollywood Life. "She was very bitchy on the first two films; she always had an attitude. So it wasn’t a surprise that she got booted from the third film."
